Pathologic T

This input is used for staging

Notes

**Note 1:** In the case of multiple simultaneous tumors, code the tumor with the greatest extension. **Note 2:** Skin ulceration does not alter the T category. **Note 3:** Satellite nodules/In-transit metastasis are coded in regional lymph nodes. **Note 4:** Tumor size must be known to assign a value of T1, T2 or T3. You may use a physician’s statement of the T category if this is the only information in the medical record. * If the tumor appears to be in the T1, T2 or T3 categories, but no size or category is specified, assign TX **Note 5:** For the following descriptions, assign the appropriate T category (T1, T2 or T3) based on the tumor size. Lesion(s) confined to dermis Invasive tumor limited to skin of penis, prepuce (foreskin), and/or glans Invasive tumor limited to subepithelial connective tissue but not involving corpus spongiosum or corpus cavernosum Subcutaneous tissue (through entire dermis) Corpus cavernosum Corpus spongiosum Tunica albuginea Localized, NOS
